No,Xanax shows up.
Hate to tell you this, but it will, it will show up as a Benzodiazipam. Which is basically all the stuff like Klonipin, Valium, Ativan, and such. If you have a current RX for it, you should be okay, unless you were driving, and had to do a drug screen on the job. Best to talk to a doc about this, preferably the one that gave you the RX.
